Disable multi requests on timeout during multi-request (#1759)

_execute_multiple_query only disables batching on JSON_DECODE_FAIL_ERROR / INTERNAL_UNKNOWN_ERROR (#1025). This change applies the same pattern to a TimeoutError raised while sending a batch: set the batch size to 1 and raise _RetryableError.
